Introducing Pokémon Sleep - a free sleep tracker with Pokémon.

The release is set for this summer.

Nintendo has finally revealed details about the Pokémon Sleep app, which the company first teased back in 2019. Initially, the release was planned for 2020, but due to the pandemic, there was no news for almost four years.

Essentially, Pokémon Sleep is a sleep tracker with gaming mechanics. If you place your smartphone with Pokémon Sleep next to your pillow at night, you'll receive a report on your sleep session with a graph of sleep phases in the morning.

The app will also assign a type to your sleep, and alongside the starting Snorlax in the app, other Pokémon of the same type will gradually appear. There are even rare ones that most players are unlikely to encounter.

Along with the app, the Pokémon Go Plus+ gadget was announced. This is an improved version of the standard Go Plus, which not only transfers physical activity to Pokémon Go but also helps track sleep more accurately in Pokémon Sleep thanks to additional sensors. Essentially, the device acts as a replacement for a smartwatch.

Inside, there's a Pikachu: its voice can be heard during the start and end of the sleep session. It also sings lullabies and acts as an alarm clock.

The release of Pokémon Sleep is expected on iOS and Android this summer. Pokémon Go Plus+ will be available for purchase in July.
